Just point to a file (.js, .css, .coffee or .styl are currently supported) anywhere in your app directory. In your view you can then just render all the css or javascript files by calling renderStyles and renderJs like this:

All files that needs to be compiled, copied (if you are bundling up a file that doesn't reside in your public/ directory) or bundled will end up in public/min/ directory. This is to have an organized way to separate whats actually your code and whats min code.
